Martin, St. Paul, Minn., assignor to Hoerner Waldorf Corporation, St. Paul, Minn., a corporation of Delaware Filed Mar. 1, 1968, Ser. No. 709,746 Int. Cl. B65d 25/04 US. Cl. 206-65 3 Claims ABSTRACT OF THE DISCLOSURE The invention discloses a packaging pad for glasses and similar objects of generally circular cross-section. The pad includes a bottom panel, to opposite sides of which are hinged straps one more in number than the objects being packed (three straps for two such objects). Top panels are hinged to the upper ends of the straps and are folded to overlie the objects. The straps are spaced apart a distance less than the diameter of the objects in order to hold the objects contained. Tabs project laterally from the bottom panel between the straps to extend beyond the diameters of the objects. The top panels are provided with similar projecting tabs.

This invention relates to an improvement in glass packing pad and deals particularly with a spacer pad used in conjunction with glasses, cups or similar fragile articles to prevent them from being damaged when sent through the mail.

Various packing means have been employed for the packaging of glasses, tumblers and the like. In the past, these items were normally shippedin considerable volume in relatively large containers, and individual packing was often placed about each such object to hold it in spaced relation to the others. Inrecent years, the production of tumblers such as plastic thermal tumblers has greatly increased. These tumblers actually comprise two shells which are sealed together adjoining their upper edges so as to provide an air space between the shells. Such tumblers are often sold in pairs or in sets of four. It is desirable that the tumblers be packed in such a manner that the major portion of the tumbler body may be viewed when the cover of the outer container is opened. It is an object of the present invention to provide a packing or spacing pad designed to encircle a plurality of tumblers and hold them in spaced relation, and in spaced relation to the walls of the outer container. The arrangement is such that when the cover of the outer container is opened, the walls of the tumblers are visible so that a prospective customer can see the coloration or other decoration on the tumblers without removing them from the outer container.

A feature of the present invention resides in the provision of a packing pad which may be wrapped about one or more tumblers to overlie the opposite axial ends of the objects. When folded into object encircling position, a substantial area of the sides of the objects is visible without removing them from the packing pad or outer container.

A feature of the present invention resides in the provision of a packing pad which in preferred form includes a bottom panel, a pair of side wall panels hinged to opposite sides of said bottom panel, and a pair of partial cover panels foldable into edge abutting relation overlying the upper ends of the objects. The side wall panels are spaced apart a distance which is substantially less than the diameters of the objects contained. The side walls are apertured to permit a substantial area of the side walls to project through the apertures. A portion of the material which is cut to form the apertures remains in the plane of the top and bottom panels, and projects laterally beyond the diameter of the objects contained to prevent the objects from coming into contact with the Walls of an outer container.

A feature of the present invention resides in the provision of a simple die cut pad which may be quickly and easily folded about a plurality of fragile articles such as tumblers and the like. The tumblers are placed upon the center portion of the pad, and the sides of the pad are merely wrapped about the sides and top of the tumblers to form a support therefor.

These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims.

In the drawings forming a part of the specification, 15 FIGURE 1 is a perspective view of a container showing I a plurality of fragile articles packed therein.

FIGURE 7 is a perspective view showing the packing pad in partially folded condition.

In the particular arrangement illustrated, each glass packing pad A is designed to contain a pair of glasses or tumblers B, and two pairs of such tumblers are contained in an outer container C. Obviously the number of glasses contained in each pad, and the number of glass containing pads contained in the outer container may vary as desired.

Also in the present arrangement, the glasses or tumblers B taper to some extent, the taper of the glasses near the upper ends thereof being less than the taper near the lower end thereof. The portions of the pad which engage the glasses is' cut to conform with the portions of the glasses which the edges engage. Thus, the edges of the straps which engage on opposite sides of each glass may also be varied according to the product being packaged.

As indicated in FIGURE 4 of the drawings, the pad A is generally rectangular in outline, and includes a bottom panel 10 connected along parallel fold lines 11 and 12 to end straps 13 and 14 respectively. The fold lines 11 and 12 on each side of the bottom panel 10 are in alignment. The bottom panel 10 is also connected along parallel fold lines 15 to intermediate straps 16. The fold lines 15 on each side of the bottom panel 10 are aligned with the fold lines 11 and 12. A generally U-shaped cut line 17 connects the end of each fold line 11 to the ad jacent end of the fold lines 15. Similarly, a generally U- shaped out line 19 connects the inner end of each fold line 12 with the adjoining end of the aligned intermediate fold line 15. Each U-shaped cut line 17 includes a out line 20 forming a portion of the edge of the edge strap 13, a out line 22 which forms a portion of the edge of an intermediate strap 16, and a connecting cut line 21. In a similar manner each U-shaped out line 19 includes a out line 23 forming a portion of the inner edge of an edge strap 14, a cut line 24 which forms the portion of an edge of an intermediate strap 16, and a connecting out line 25. In view of the fact that the cut lines 20 and 22 diverge outwardly from the ends of the fold lines 11 and 15, the U-shaped cut lines 17 define substantially trapezoidal projecting tabs 26 projecting beyond the sides of the remainder of the bottom panel 10. Similarly due to the fact that the cut lines 23 and 24 diverge outwardly from the adjacent ends of the fold lines 12 and 15, the U- shaped cut lines 19 define substantially trapezoidal tabs 27 projecting beyond the sides of the remainder of the bottom panel 10.

Partial top panels 29 are connected to the side or edge straps 13 and 14 and the intermediate straps 16 along aligned fold lines. The straps 13 and 14 are connected to the partial top panels 29 along aligned fold lines 30 and 31. The intermediate straps 16 are connected to the partial top panels 29 along fold lines 32 which are aligned with the fold lines 30 and 31. Generally U-shaped cut lines 33 connect the inner end of each fold line 30 to the adjacent end of the aligned fold line 32. Genthe end edges 42 of the blank. The cut lines 21 and 25 on each side of the bottom panel 10 are also in alignment and are parallel to the end edge 42 of the blank.

The cut lines 35 continue beyond the transverse cut 111168 37 to meetrthe ends of the cut lines 20, forming the inner edge of each edge strap 13. The cut lines 39.

continue beyondthe transverse cut lines 41 to communicate with the ends of the cut lines 23 to form the inner edges of the straps 14. In a similar manner, the cut lines 36 continue to communicate with the ends. of the cut lines 22, and the cut lines continue to communicate with the ends of the cut lines 24. This arrangement provides generally trapezoidal openings 47 between the projecting tabs 26 on the bottom panel 10, and the opposed projecting tabs 43 on the partial top walls 29 formed by the cut lines 33. Similar openings 44 are provided between the ends of the tabs 27 projecting from the bottom panel 10 and the opposed tabs 45 projecting from the partial top panels 29. The arrangement is such that the width of the bottom panel 10 combined with the length of the tabs 26 is greater than the diameter of the the blank is folded along thealigned fold lines 11, 12,

and 15 on one side of the bottom panel 10 to extend upwardly at right angles thereto. The correspondingtop panel and the projecting tabs 43 and 45 integral therewith is folded over the upper edges of the glasses B as indicated in FIGURE 7. The opposite straps 13, 14 and 16 are then folded upwardly and the top panel 29 connected thereto is pivoted along the aligned fold lines 30, 31 and 32 so that the edges 42 of the top panels 29 meet in edge abutting relation as indicated in FIGURES 2 and 3 of the drawings. The package then appears" as indicated in FIGURE 2 and the package may beinserted into an outer container C for shipment-When thus contained, the glasses B are suspended out ofcontact with j all of the walls ofthe outer container C- and the container C is proportioned to contain one," two, or a film shown in FIGURE 2, two

If it is desired, a strip of tape 46 may extend across assembled form prior to placing the packages in the outer container, and to hold the package assembled during removal from the outer container. The tape 46 is actually unnecessary from a shipping standpoint, as the pads are held in proper form by the outer container C during shipment;

As will be noted, the top and bottom walls of the pad extend between" the ends of the glasses 3 and the side walls of the container C cushioning the glasses from axial movement. The straps 13, 14, and 16 engage the glasses B on opposite sides of center, and the openings between the straps are narrower than the width of the glasses so that the side walls of the glasses are held from lateral movement.

The projecting tabs 26 and 27 on the bottompanel 10, and the tabs 43 and 45 on the top walls 29 suspend the glasses B out of contact with the two opposed walls of the container while the edge straps 13 and 14 hold the glasses in spaced relation to two parallel right angular walls of the outer container. As a result, the pad is very effective in preventing injury to the objects B during shipment. 5 In; accordance with the patent statutes, I have described the principles of construction and operation of my glass 1 packing pad; and while I have endeavored to set forth the best embodiment thereof, I desire-to have it understood that obvious changes may be made within the, fol- 30 lowiiig claims without departing from the spirit of my.
